Eg: In Canada people are trying to push the Prime Minister into releasing Meng back to China. But the government is strictly separate from the legal/court system to avoid the type of corruption one sees the US Dept of Justice accused of right now. So yes, he very well might be able to push the matter through loopholes or influence, but the very same people pushing him to do it would also decry corruption and call him a dictator if he did so. So he won't overstep that boundary.
Additionally, I used to provide technical expert witness services in certain types of court cases. I had to state only things that I can back up as part of my expertise. I had to use the word 'apparent' and 'presumed' a lot, even when file names were so extremely obvious. I couldn't refer to a hacker as a hacker in certain contexts - they're simply "suspects" etc. As a technical expert, I spoke to the technology and not the person or any literal content.
It's exactly the same reason you see the word "alleged" used in the news even when it is super obvious the "alleged" facts are obviously true -- Jurisdiction and authority to state specifics as fact.
You must be confusing Tallinn with some other city - Estonia does not and has not had any nuclear power plants.
The map covers Sweden, Finland, Estonia, Latvia and Russia. Estonia and Latvia have no nuclear power or weapons programs, and the first four are EU countries where staying silent about an incident would be very unlikely. That leaves Russia.
Interestingly enough the possible source area includes the Arkhangelsk naval base, where the Russian nuclear submarine fleet is stationed. An incident there may explain the lack of information.
As for claims of the fission products coming from a "civil source", I don't think enough is known about Poseidon's reactors to rule that out. I could be wrong, but as far as I've read the details of that reactor are up in the air (besides being small, obviously.)

According to graphs here https://www.stuk.fi/web/en/topics/environmental-radiation/ra... it rose to 0.18 µSv/h, not mSv/h, which is just slightly above normal in the area (0.13-0.16 µSv/h depending on station, looks like)
Do you have source for this? This is likely just normal natural background radiation.
Seems there is unit confusion as it only rose to 0.18 µSv/h in Helsinki, not to 0.18 mSv/h which would exceed Chernobyl impact.
It's either one of the old Chernobyl-like pressure water reactors in Tallin or St Petersburg. Really interesting is also why the control commission in Vienna is not allowed to call them out.
